  4. //                This file contains the source code for the DirectCopy File/Resource Info
  5. //                ScriptCheck extension function.  Since our source files are in the regular
  6. //                format (not compressed or otherwise changed and unreadable by normal
  7. //                means) we can get the information we need directly from them.  If you are
  8. //                writing your own ScriptCheck extension for your own file format, you will
  9. //                need to provide routines that know how to read your file format.
